In most cases, the eggs are contained within the tapeworm segments, and unless they are broken open, they may not appear on the fecal exam. Tapeworm eggs may be difficult to detect on a routine fecal exam. Dogs will sometimes lick their anus, or scoot on the ground, on rugs, or other hard surfaces. Pets may experience irritation or itchiness around the anus from passing the tapeworm segments. As they dry, they look more like sesame seeds. When fresh, these segments are white or cream colored, can move and look like grains of rice. It can take up to one month for the tapeworm larvae to reach maturity and start shedding eggs.Īn owner may become aware that his or her pet has tapeworms by finding tapeworm segments stuck to the fur around the pet’s anus, in the pet’s bedding, or in the pet’s feces.
While in the environment, flea larvae eat the tapeworm larvae, and pets become infected when they ingest an adult flea while grooming, biting or chewing on their skin. The most common tapeworm found in dogs and cats is associated with fleas. Once in the environment, the segments break open, releasing the eggs, which will develop into tapeworm larvae. Each segment contains numerous tapeworm eggs. Tapeworm segments detach from the end of the adult tapeworm and are shed in the pet’s feces. Several species of tapeworm can infect pets but the most common offender is the tapeworm know as Dipylidium Caninum. An adult tapeworm can reach six inches or more and has the appearance of a white piece of tape or ribbon. Tapeworms are long, flat, parasitic worms that live in the intestines of dogs and cats.
